A solution to the plugging of UV flat printer nozzle

Users who have used a UV flat printer may be able to remember the phenomenon that printing head plugging often occurs
after a period of time when the weather is too high or too low in summer or
winter.How to solve this problem?

The blockage of inkjet printer can be
roughly divided into two categories:soft plugging and hard blocking.

1.soft
clogging

Soft plugging refers to the failure of ink on the sprinkler
due to various reasons.If only attached to the nozzle of the nozzle surface,you
can turn on the machine flicker setting,the 8Hz to 1K,let its flash 2 minutes
later back to 8HZ,after a number of flash can be restored.Its advantages are
easy operation,quick and no physical damage.The disadvantage is that the cost
is higher and more wasteful ink.

Another way is to use the print head cleaning function in
the printer application tool to clean.Its advantages are simple and quick
operation,and the disadvantage is that the cleaning effect is not very
satisfactory.

2.Hard
clogging

The hard colgging refers to the blockage caused by chemical
coagulants or impurities in the nozzle.The troubleshooting method is more
difficult.At this time,the following two methods can be used to solve the
problem.

Working principle:dissolve the ink particles one by one
with medium strength organic solvents.Note that 95% concentration of organic
solvent alcohol must be used,otherwise it will backfire.

Solution:first find a metal container with a flat bottom
and add a little 95% concentration of organic solvent alcohol to the
container,and the alcohol is limited to the stainless steel edge of the
printing head(notice that the main plate of the nozzle is not exposed to
alcohol).The soaking time is usually 5 to 15 minutes The syringe is injected
into the print head to achieve the purpose of cleaning up the dry ink head.

2.2 Ultrasonic instrument cleaning

Scope of use:serious congestion

Working principle:use ultrasonic cleaning agent to produce
strong ultrasonic wave,make the water molecules vibrate violently,and then
dissolve the small dry ink particles to dissolve in water,so as to achieve the
purpose of cleaning.

Solution:put the inkjet print head gently into the cleaning
machine and add a special printing head cleaning solution.The cleaning solution
is limited to the stainless steel edge of the printing head(attention should
not let the main board contact the special cleaning liquid).The advantage is
that the cleaning effect is very ideal,the printing head which has been blocked
for many years can be cleaned,and the operation is very simple.The disadvantage
is that the maintenance cost is high and the cost is more expensive.
